System-Specific DDR4 ECC RDIMM Kit

This 256 GB kit contains two 128 GB registered DDR4 modules built for the THINKMATE SBGrid-CryoEM workstation. Error-correcting code and registered buffering protect data integrity in mission-critical workloads. IT professionals select this memory to maximise capacity on qualified platforms.

DDR4 3200 Registered Interface Limits

The modules run at DDR4 3200 (PC4-25600) with a CAS latency of 22 at 1.20 V. Registered DIMMs add one clock cycle of command buffering, so the memory controller must support registered ECC RDIMMs. A 4Rx4 organisation increases electrical load per channel, which can reduce the maximum number of populated slots.

Pre-Installation Compatibility Checks

Verify that the workstation accepts 288-pin DDR4 RDIMMs and supports 128 GB per slot at 4Rx4 density. Confirm the BIOS revision lists this part number or an equivalent qualified module. Ensure enough free DIMM slots exist for the two-module kit without exceeding the platform's rank-per-channel limit.

Questions about this item

Should I pick the 256 GB kit or a smaller capacity for my THINKMATE SBGrid-CryoEM?

The kit contains two 128 GB modules for a total of 256 GB; choose it if your workload needs that much memory and your motherboard has two free RDIMM slots.

What does the 3200 speed rating deliver in the workstation?

The modules run at DDR4 3200 (PC4-25600) with CL22 latency, providing the rated bandwidth when the platform’s memory controller is set to that speed.

How does the 288-pin RDIMM interface affect installation?

Each module uses the 288-pin DDR4 RDIMM form factor with registered buffering and ECC, so it fits only motherboards designed for registered DDR4 server memory.
